OBJECTIVE:To extract and purify organic acids with macroporous resins from Folium Isatidis.METHODS:Folium Isatidis was extracted with 70% aqueous ethanol(pH=2)by Soxhlet extraction.The process was optimized by employing orthogonal test design with the content of anthranilic acid as the index.RESULTS:The resin HPD100 had much better adsorption capacity and desorption ratio by using 3 BV 60% aqueous ethanol to extract organic acids in Folium Isatidis than other resins.The results showed that HPD100 possessed the better ecomic under the concentration of sample 0.18mg?mL-1,the condition of pH 3.5,and flowing rate of 2BV?h-1.CONCLUSION:Macroporous resin HPD100 may be value of isolating and purifying the organic acids from Folium Isatidis.

Objective To investigate the association of the tumor necrosis factor ligand superfamily member(TNFSF)4 gene polymorphisms rs3861950 and cerebral infaretion in Hunan area.Methods The frequencies of the genotypes of rs3861950 were detected utilizing real-time fluorescent PCR method based on TaqMan probe.Subiects examined were composed of 287 patients and 285 healthy individuals.Results There were significant differences in TNFSF4 gene rs3861950 C→T site polymorphism and allele frequency between the subjects and the controls,the distribution of CC genotype was significantly higher in the former (7.7%)than in the later(2.1%,X2=9.553,P=0.008),so was the frequencies of C allele(0.190 vs 0.137,X2=5.887,P=0.015).Moreover,there were significant differences in the distribution of genotype and the frequencies of allele between the subgroup of cerebral thrombosis and control group ( for the distribution of genotype X2=9.396 P=0.009,for the frequencies of allele X2=6.134,P=0.013).Logistic regression analysis showed that the risk factor of CC genotype was 3.7 times higherthan others(P=0.002.OR 3.706).Conclusions TNFSF4 gene SNP rs3861950 is associated with cerebral infarction and C allele is considered to be one of independent risk factors in the Han population in Hunan Province.

Radix Isatidis (Banlangen in Chinese), used to clearing away heat and toxic material, is a traditional Chinese medicinal (TCM) herb. It is frequently used for preventing and treating infectious diseases caused by viruses. To provide scientific basis for the effect of Radix Isatidis on infectious diseases, the traditional effect and new research development on pharmacological activities are summarized in the review. According to the existed problems in the clinical application, the weak links and shortages of quality research and industrialized production of Radix Isatidis are discussed. It could present the new ideas for improving the technology of Radix Isatidis preparation, and promoting the rational use of the preparation in the clinical treatment.

OBJECTIVETo compare the outcome of non-operative treatment with the outcome of surgical intraventricular drainage for patients with posttraumatic hydrocephalus including complications, mortality and favorable outcome.

METHODSThirty-nine patients were assigned to a nonoperative treatment group and 38 patents to a surgical intraventricular drainage group. Each patient's outcome was evaluated 3 years after treatment by using Glasgow Outcome Scale.

RESULTSIn the nonoperative treatment group the rate of favor able outcome (good recovery or mild disability) was 89.74% (35 of 39 patients) and the mortality was 2.56% (1 of 39 patients). In the surgical intraventricular drainage group the rate of favorable outcome was 71.05% (27 of 38 patients) and the mortality was 13.16% (5 of 38 patients; P<0.05). Mortality was not significantly different between the two groups.

CONCLUSIONSNonoperative treatment may be better than surgical intraventricular drainage for patients with posttraumatic hydrocephalus.

Objective To investigate the influence of social cognition and interaction training(SCIT) on psychiatric symptoms, social function and life quality of patients with schizophrenia in remission. Methods 90 patients with schizophrenia were randomized into intervention group and control group. Combined with primary medication, patients in intervention group were treated with SCIT for 10 weeks while patients in control group were treated with routine mental supportive treatment. Patients' psychiatric symptoms, social function and life quality after treatment were observed. Results Scores of positive and negative syndrome scale (PANSS), social disability screening schedule(SDSS), family assessment device (FAD) and general quality of life inventory (GQOLI) in two groups before intervention were not significantly different(P＞0. 05). Compared with those before intervention, scores of positive syndrome, negative syndrome and total score of PANSS decreased significantly in two groups respectively (P＜0. 05) and these indicators in intervention group improved more significantly when compared with control group (P＜0. 05). Scores of SDSS and FAD in intervention group decreased when compare with those before intervention and were lower than those in control group(P＜0. 05). After intervention, scores of body function, physiological function, social function and quality of life in intervention group increased significantly (P＜0. 05) and were higher than those in control group after intervention (P＜0. 05). There were no significant differences of scores of material life satisfaction between before and after intervention or be tween groups (P＞0. 05). Conclusion SCIT could improve the social function and quality of life in patients with schizophrenia in remission significantly and could relieve the clinical symptoms of patients with schizophrenia in remission to some extent.
